Investigation of physicochemical properties of dimeric (gemini) surfactant

In this study, four different cationic gemini surfactants were synthesized and firstly, the krafft temperature (TK) and critical micelle concentration (CMC) values of the synthesized surfactants (YAM) were determined by the conductometric method. Aggregation number (Nagg), defined as the aggregation of micelles in beer, was determined by the fluoremetric method, and surface tension was determined by the tensiometric method. The foam capacity (FC) and foam stability (FS) of the synthesized gemini surfactant solutions were examined by measuring the foam volumes. Additionally, the dye solubilization ability of these substances was tested with the water-insoluble Sudan Red B dye. The corrosion effects of surfactants called 12-3-12, 12-3(OH)-12 and 12-2-0-2-12 on carbon steel in 1 M HCl were determined by mass loss method, electrochemical impedance spectrometry (EIS), tafel polarization ( TP) and scanning electron microscopy (SEM) methods.
